I've said it many times before: Toure has been unfairly criticised by our fans simply because of those 2 bad mistakes around January time last season. Apart from the obvious lack of pace, he is a very decent defender and is less prone to making silly mistakes than Skrtel. It's no coincidence imo that we always look a lot more solid at the back when he's in the team.
I think we should consider a Toure/Lovren partnership for the game at Chelsea. Toure/Sakho could also work very well once he's back from injury. Skrtel, Sakho and Lovren could all really do with someone beside them that is a bit of a leader and I think Toure provides that.
I definitely want to see Borini starting against Chelsea (unless Sturridge is fit to start obviously). Whilst he doesn't really provide a lot on the ball, his movement moves defenders around and creates space for our other players to do their thing. A Balotelli/Borini partnership could work, although I doubt BR would play a diamond against a top team when we're in the form we are currently in, so I would have Lallana and Sterling flanking Borini.
Dunno what I'd do in midfield tbh, I'm undecided. I like how Can brings the ball forward and drives into space, but his passing has a tendency to be a bit wayward. I think I'd just go back to what worked best last season: Gerrard behind Hendo and Coutinho. That said, I think Lucas deserves a chance of Gerrard one day, but it obviously isn't going to come against Chelsea.
